| Abstract Scope |
Large scale directed energy deposition (DED) is a technology of interest to replace expensive and long lead-time forgings. Often the mechanical properties are not as robust as forged or wrought materials making it a challenge to insert into production. The energy and defense industries have a desire to achieve wrought properties from the DED additive manufacturing (AM) process using commercially available alloys. Utilizing semi-quantitative EDS, EBSD, and static mechanical testing the authors will share results from using periodic inter-layer forging forces to enhance the microstructure and mechanical properties in comparison to as-built gas metal arc welding (GMAW)-DED of austenitic 316L stainless steel. |
